I am a woman who is bisexual and is married for almost 4 years. Is it good to be bisexual in a marrige?

What is "good"?

The terms of your marriage are between you, your partner, and your god. If being bisexual works in YOUR marriage, then it's good for YOU.

If, however, it causes problems in YOUR marriage then it's bad for YOU.

Communication, trust, love and honesty are things that I'd call good to have in a marriage. Everything else is user defined.

As long as you are happy and faithful to your husband.
If you can not control your bi sexualness and your husband feels it is a problem then I would see it as no different than what one should expect in a heterosexual relationship.

What does your husband think about it, does he have any issues with you seeing other women ? If he was, would you care if he was seeing other men ?

She doesn't exactly say she is acting on her desires

I don't think it is necessarily "good" or "bad" to be bi in a marriage... only the same dangers to be conscious of in regular marriage.

You have to build trust in a marriage.

What difference does being bisexual in your marriage make? You do know that the same problems will arise if you are strictly homosexual? You may be attracted to women, but do you act on those desires? If so then the problem is not about you being bisexual it is about you being unfaithful in your marriage. Just think about it.

If you are bisexual there is nothing to do about it. You chose to marry a man and hopefully that man is your soul mate, and marriage it is really not about the sex of the other person it should be about the spiritual connection you share with that person.

I have two friends and they are both gay. I mean that one is a woman and one is a man. They had never been with the opposite sex prior to being with one another. I know it sounds crazy, but it's true. They connected so well that they married and when I asked them about it they told me it is not about the other person's body, it is about their spirit. They are soul mates and they could not see themselves being with anyone else. So they are strictly faithful to one another.

I hope that helps
Good luck
